    What is considered an acceptable humidity for a reloading/gun storage room?

    what is considered too high?

    right now my reloading room is at about 45% humidity, the rest of my house is about 20%.

    If 45% is bad, what are some things I can do to protect my guns and reloading supplies?


    thanks,
    Scott

    The critical humidity for NaCl is around 75% so you are more than safe at 45%. Basically, if you can keep the RH below 60% and take reasonable care of your firearms and reloading equipment you'll be fine.

    According to the NRA:

    50% humidity at 70 degrees is considered ideal "Arms Museum" storage conditions.
    Any dryer then that, and you will have problems with wood stocks drying out and shrinking / checking.


    Seems your reloading room is about right, and the rest of the house too dry.

    When HVAC engineers design a/c systems for large spaces such as museums, airports, libraries etc. they have to take into account the fact that the load on the cooling system changes as a function of how many people enter/leave the space. This can be a big design challenge for some buildings. However, I can assure you that for the typical homeowner, 60% RH is sufficiently low to prevent corrosion and you'll just be wasting energy maintaining your house at 50% RH. As rcmodel mentioned, you don't want the humidity to be too low either if you have rifles with wood stocks.

    60 to 65% is what we shoot for at the hospital in areas we control it. At 70 or 75% they will shut down OR. I forget offhand what the minimum is.

    45% humidity is a dry day here in the Northeast. I doubt my reloading area in my basement ever goes much below 50%, even in the winter. I've never had any problems with my reloading components, loaded rounds, or rust on my guns.

    FWIW - Rock Island Arsenal's Firearms museum tries to keep a constant 55-60% humidity.

    I have a dedicated office/gunroom and I run a small dehumidifier about 8-9 months a year set at 55% RHL. I never had any corrosion problems or dried stocks. Have been waiting also for RCmodel's visit to see if affects his wooden legs in any way. If so I have plenty of WD40! :D

    Having lived in northern NV, where the average humidity was always below 20%, I have never had an issue with wood stocks. Now living in FL, where the average humidity is running around 90%, I keep everything inside that I can, even thbough I physically reload in the garage
